PUMP MECHANISM.

'inf t Specification of Letters Patent. i

Patented Oct. 12, 1915.

Application filed June 3, 1914. Serial N o. 842,712.

dust collector wherein the dust laden air f will be passed through the samejfor separating the dirt from the air to clarify it prior to the delivery of the same from the machine, the pump for creating a suction `within the collector being of novel form to insure 'service and durability.

` Another object of the invention is the provision of a pump mechanism of this character wherein the same is positive in action and practically frictionless when operatingi.

A "further object of the invention is the provision of a pumpmechanism of this character which is extremely simple in construc ion, thoroughly reliable and efficient in its operation, and inexpensive in manufacture.

lith these and other objects in View7 the invention consists in the construction, combination |and arrangement of parts as will be hereinafter fully described, illustrated in the z iccompanying drawings, and pointed out in the claims hereunto appended.

ln the drawings: Figure 1 is a side elevation of a machine constructed in accordance with tle. invention. Fig. 2 is a verticai longitud nal sectional view through the collector. Fig. 3 is a vertical transverse sectional view thereof. Fig. et is an enlarged vertical sectionalvicw through the pump. Fig. 5 is a sectional view on the line 5-5 of Fig. L Fig. is a perspective view of the hinge plates. Fig. 7 is a perspective view of the eccentric.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, the dust collector comprises a rectangularshaped or box-like casing 10 formed with a base 11 for supporting the same. Formed in one side of the case l0 are suitable ports 12 which are adapted to be `normally closed by means of cover plates 13 detachably secured to the outer face of the case in any suitable manner and on the removal of the plates 13 access may be had to the interior of the case for the cleaning of the same.

Arranged v,within the case 10 are spaced vertically disposed partitions 14 and 15 respectively, the partitions 14 being extended from the top ofthe case toward and termiJ nating spaced from the bottom, while the partition 15 extends from the bottoni :toward and terminates spaced from the tope of the case so as to form communicating compartments 16, 1 7, 1S and 19 therein.V By reason of the internal arrangement of the case the air introduced into the collector is compelled to pass therethrough along the circuitous course indicated by the arrows. Leading to the 'compartment 16 through the top of the case 10 is an inlet pipe 20 which is adapted to extend to or into a closure so that on the working of the collector dust laden air will be conveyed through the pipe 20 into the case 10 for the separation of the dust from the air in a manner presently described.

Mounted upon the top of the case 10 directly above the compartment 19 is a pump having an intake pipe 21 leading from the compartment 19, and an exhaust pipe 22 which may extend to any desirable point, the pump being hereinafter fully described. The pump comprises an outer cylinder 23 supported by a hollow base or pedestal 24 which is fixed in any suitable manner to the top of the casing 10 and within the cylinder 23 is eccentrically mounted an inner cylinder Q1', the same being supported upon eccentrics Q5 integral with a .driving shaft 26 which is passed through theV ends of the outer cylinder 23, the shaft being surrounded by means of bearing balls Q7 suitably seated in the bearings Q8 formed on the ends of the outer cylinder. Likewise surround ing they eccentrics 25 are bearing balls 2S) which are held in any suitable manner in the openings for receiving the eccentrics in the ends of the cylinder Q4. On one end of the shaft 26v is tted a vbelt pulley 30 over which is trained an endless belt 31. the same being trained over a belt pulley 32 fixed to a shaft 33 sfuitably journaled in a bar 34 mounted upbn an adjustable supfport 35 swingingly connected to the case 10 at the opposite end thereof, the support 35 being adjusted by means of an adjusting device 3G which enables the tightening of the belt 31 on the pulleys to avoid slipping thereover.

Fixed to or integral with the inner cylin 'the lei readily der aiy one point ol'Y ite periphery is a, blade or wingv 3'( which is cdextensive with th ot the said inner l:ylinder and is hollow base or pedestal the tree edge ot the proirried into the L" ol thi punip case 23, said plate or wing' 3T beingl formed with a circular portion 255 which looselylits within a eorreepondingly shaped groove 3) formed in an upturned flange il() on a hinged plate 'ljl 5o that the wing or blade. will have linuelilepoint connection with each other. The opposite upt-urned `flange ot the plate Vtornied with a groove rounded portion l2 of a hanger 4l which tired integral with one wall ot the pedestal and in this manner the said plate ll can swing to allow' tor the variance in the etrolux o'l` the wing or blade during the eceentrir rioveineiit oi: the inner cylinder Q-l within the outer cylindrr 2B oi' the pump..
